Thank you.Compressed air is measured in two ways..... pressure and volume.
Pressure is measured in PSI. Volume is measured by CFM....
Spray guns need the correct amount of air to run properly. Even a cheap gun needs those parameters. When I kick the air pressure up to say 37 (which is the most) its because I want to dust the paint on. It gives the car more of a satin finish. By increasing the air pressure the paint dries incredibly fast and can't settle which is fine for a multi-layer top coat that will be clear coated. You are shooting primer with this gun which needs to properly adhere to the surface or you are eliminating any purpose of primer and might as well use primer out of a spray can. You need to shoot the primer at 26 at the highest.
Compressor and Gun go hand and hand. If you had a Tekna Pro you would still get terrible results with a compressor that can't keep.
Send photos of the rust and I can tell what should be done.Thanks for all the input everyone.
I cannot throw money in like nothing, but if I am going to fix the rust spot, I want to do it right.
I will look into it more and weight on what options I can have based on my budget.
You might get away with it on the doors and hood and for sure on the top because no one will see it but no way it doesn't eventually crack on the side with time and exposure to different climates. .Of the two, epoxy is a higher-strength substance that prevents a surface from moving. Though epoxy is strong, it will crack on surfaces that frequently move. Urethane retains flexibility. Structures that contract or expand with seasons or temperatures are better suited for urethane.
Just got my Husky Gravity HVLP Spray Gun spec is 4.3CFM @ 40psi) .Something like this would be the minimum. Compressors build up water in the tank over time, and it can end up in the line. Liquid water going through the nozzle will cause spotting on the paint.

I would mount the water separator vertically in line to the gun rather than try to attach it to the gun. Pressure regulator should be downstream of the separator, at the gun is OK.I just messing around with the HVLP gun and filter, and wonder if i can mount the filter horizontal to the gun? If not, i need an angle fitting to my spray gun, but what if I spray horizontal surface?

I also bought the regulator, so I can keep the pressure at a specific PSI at the gun.
I am abit concerned (hopefully I just dont know and worried too much)...
Thanks all!!
- Can I just mount the filter on the compressor side? So it can stay stationary while I spray?
- When I spray, especially near bottom of van and roof, if the filter is fixed to the gun, its impossible to stay horizontal... So maybe orientation doesn't matter?
I will mount water seperator near the compressor, then hose, and the regulator right at the gun.I would mount the water separator vertically in line to the gun rather than try to attach it to the gun. Pressure regulator should be downstream of the separator, at the gun is OK.
